velocity of the vehicle. and the diameter of the track. Covering the moon in solar panels for electricity and then generating food from that might be substantially easier as solar panels can survive in a vacuum. some of which threaten to be catastrophic in the extreme. Other answers outline the key points of using robots and harvesting light with plants and solar panels, but one interesting technology is "Solar Foods" (https://solarfoods.fi/). Incremental accentuation of gravity The question of the second law of thermodynamics.

If you can make it dense enough (with technology that’s indistinguishable from magic), you can still have a pretty useful surface area and also 1G of gravity, so that it can hold on to an atmosphere indefinitely and be healthier for humans to live on it. yes, 200-fold avg. It only takes a minute to sign up. For Phase 2, drop an army of robots on the surface and have them scavenge raw materials (carbon dioxide, water, metals and trace minerals) to stockpile in the roofed caves. Terraforming the Moon: What Has To Change? But i don't know a lot of things, so i'm just not sure. Can a precognitive dodge modern firearms? A Makes a lot of sense, at far less risk and cost. Idea 2: Perhaps we could put a gigantic dome on the moon that completely covers it, but just more than likely is perhaps the size of a small city or large town. simulate Earth gravity, likley optimal to human health, longevity. It's been suggested by this firm that you could create foodstuffs without agriculture at all, supplying the needed energy by electricity to go from CO₂ + water to a foodstuff. Lunar pioneers would find it far more cost effective to make small contained volumes very habitable for development, rather than to make the entire inhospitible volume imperceptibly more habitable. This might imply a critical-path thru comet & asteroid mining to get things completely free of Terran dependencies. How can I efficiently manipulate digits in a string without using RegEx in Java? Temperature and climate “under” the gas giant in a tidally locked moon, A semi-habitable Mars and the differences between the plains and the craters. @GKFX, thanks for keeping me honest. Is the typo in the 25th amendment significant? @cmaster That is not entirely true. So instead of fungi, phase 3 should involve algae or genetically enhanced simple plants which can somehow endure the hardships of lunar cave life.
